During his time as an elected official, Studen was a member of the far-right Serbian Radical Party (Srpska radikalna stranka, SRS).
Studen appeared in the thirteen position on the Radical Party's electoral list for the Novi Sad division in the 1993 Serbian parliamentary election.
[6] The Socialist Party of Serbia (Socijalistička partija Srbije, SPS) won the election, and the Radicals served in opposition.
[9] In February 2000, in the aftermath of the Kosovo War, he was one of a number of Serbian ad Yugoslavian officials placed on a six-month travel ban to European Union countries.
Serbia's government fell shortly after the Yugoslavian vote, and an interim ministry was established that did not include the Radicals; Studen's term as deputy minister came to an end in October 2000.
A new Serbian parliamentary election was held in December of the same year; prior to the election, Serbia's electoral laws were reformed such that the entire country was counted as a single electoral division and all mandates were awarded to candidates at the discretion of the sponsoring parties or coalitions, irrespective of numerical order.
